This type of emergency lighting is more rare than the surface mount type in the other pic as most sections of the subway did not have the height for a drop ceiling. When a drop ceiling was used however, special 1X1 recessed squares were used as the emergency lights...possibly to match the 1x4 troffers that are also common. The troffers are slightly rare too, most 1x4 troffers I've seen have the ballast in between the lamps and have two lamps.
Aside from the missing doors on the troffer and the other recessed light and the T8 conversion, this is still more or less in it's original 1963 condition. Most of the 1x1 ceiling tiles have since been replaced with aluminium slats (due to asbestos?) and the recessed squares removed when T8 came.
About Those Troffers...
Remember how I said the 1x4 troffers were missing the doors? Well, here's a bunch of them. They're not your average run of the mill troffer lens too. These have a full length hinge on them and are latched in place with screws. The sealing and the rippled frosted glass is a nice touch too.

Anyway, cool pic here! Looks like this ceiling could use some help, though!
And yes popcorn ceilings along with the other types of drywall texture commonly used asbestos up to the late 70s.
BTW, slightly OT but I went up there today...that house has since been replaced by an (ugly) 2-story monster...it isn't finished yet but I can pretty much tell what it will look like.

Yeah you don't really see incandescent installed with fluorescent anymore.
